Upgrading Disk Drive Firmware In An Hp Continuous Access Eva Environment; Saving Storage System Configuration Information - HP 6400/8400 Software Manual

Upgrading disk drive firmware in an HP Continuous Access EVA environment

When upgrading disk drive firmware in an HP Continuous Access EVA environment, the following
requirements must be met. See HP StorageWorks Continuous Access EVA implementation guide for
more information.
• Verify that all DR groups are not failsafe mode enabled or in the failsafe locked state (DR group
failsafe mode should be disabled).
• Suspend replication and disable the intersite link or modify zoning to isolate the source array from
the destination array.
• Upgrade the disk drive firmware on the destination array
• Re-establish intersite link communication between the arrays and resume replication, allowing the
DR group merges to complete.
• Perform site failover.
• Suspend replication and disable the intersite link or modify zoning to isolate the source array from
the destination array.
• Upgrade the disk drive firmware on the new destination array (before site failover, this was the
source array).
• Re-establish intersite link communication between the arrays and resume replication, allowing the
DR group merges to complete.
• Perform site failback.

Saving storage system configuration information

Estimated time to complete: 10–15 minutes
When to perform: As close as possible to the upgrade
Before starting the upgrade, collect and save your current configuration information. This information
can be used to restore the existing configuration if necessary. The configuration data is saved to a
series of files stored in a location other than on the storage system. HP Storage System Scripting Utility
(called the utility) is used to collect configuration information.
This procedure can be performed from the management server where HP Command View EVA is
installed, or from any host running the utility to communicate with the HP Command View EVA.
NOTE:
You will need the IP address or name of your management server to run the utility.
1. Double-click the HP Storage Systems Scripting Utility desktop icon to open the utility. When
prompted, enter Manager (management server name or IP address), User name, and Password.
2. Enter LS SYSTEM to display the arrays managed by the management server.
3. Enter SELECT SYSTEM system name, where system name is the name of the storage system.
The storage system name is case sensitive. If there are spaces between the letters in the name,
quotes must enclose the name. For example, SELECT SYSTEM "Large EVA".
